Glendower Street Congregational is a chapel of exceptional sophistication and elaboration of design and one of the earliest Italianate chapels in Wales. The main entrance facade to the road is of three bays with the central entrance flanked by square section Tuscan Order attached columns, with round attached Corinthian-style columns flanking the central doorway and round-headed window above in the space between. These unusually elaborate full-height columns support a cornice crowned by an open balustrade. This flat top to the entrance wall is continued over the recessed flanking bays which have rectangular windows on the ground floor surrounded by a raised architrave and round-headed windows above. The wall is stuccoed. This chapel was built in 1834 and rebuilt in 1844 by architect William Armstrong and builder Benjamin Lawrence of Monmouth. In 1996 the chapel stood derelict but in 2002 the building was transformed into a dwelling, winning awards for quality of design and renovation work (ex inf. current occupant). There were originally galleries on three sides of the interior. Glendower House is now Grade 2* Listed as an outstanding 1840's classical chapel which has retained its character destpite conversion to domestic use.
